First, welcome to GT Planet.
You might want to introduce yourself, as it would make it easier for us to understand who you are and why the modifications you bring to us are valuable.
Please, I am curious, what is a "unlicensed physics"?
Leftover generics? again curious, what do you mean by that?
So, you alter .ini files in the data folders, congratulation. Where do you get your data from and why should we use your alterations?
Thank you in advance for the explanation and welcome again to our fun little community.
